Which type of materials are more likely to dissolve in water due to their interaction with water molecules?

• A. Hydrophilic
• B. Hydrophobic
• C. Metallic
• D. Nonpolar

Answer: (A)

Verified step by step guidance

1. Understand the nature of water: Water is a polar solvent, meaning it has a partial positive charge on one side and a partial negative charge on the other, due to its bent molecular shape and the electronegativity difference between hydrogen and oxygen.
2. Identify the types of interactions: Polar molecules or ions can interact with water through dipole-dipole interactions or hydrogen bonding, which are strong interactions that facilitate dissolution.
3. Define hydrophilic materials: Hydrophilic substances are those that have an affinity for water. They are typically polar or ionic, allowing them to interact favorably with water molecules.
4. Contrast with hydrophobic materials: Hydrophobic substances do not interact well with water. They are usually nonpolar, meaning they lack the charge separation needed to interact with the polar water molecules.
5. Conclude which materials dissolve: Based on the interaction types, hydrophilic materials are more likely to dissolve in water due to their ability to form favorable interactions with water molecules.
